I hope someone can help!!! 2012 Super Duty 6.7 PS SRW.
Truck is pulling hard to the right when I brake. History: Left Front Bearing went out last week and the dealer replaced it. Just that side....yes I know to replace them in pairs but when the bill is $850 for one side.....Anyway....was on my way to get my tires rotated and balanced when I noticed the hard pull. Had them rotated and balanced with no difference. Took back to dealer. The front right side is braking 35% harder than the left so they think it's caliper since they "checked" the suspension and all other things it could be. I just replaced the calipers 15,000 miles ago. They said "did you buy them here?" I said yes but did them myself......they said "no worries, we will replace them under warranty". They did and said you are all set. No change....still pulling hard to the right when I step on the brakes. Thoughts? what am I missing? Ball joints checked out. Right Bearing checked out. Could not replacing both HUBS at the same time cause this???

 

Probably a restriction in the LF hose or line.

No.

 

Air in the brake lines? On the left side? How "normal" is the pedal feel, compared to before they swapped the hub bearing?

 

Feels about the same. I had that thought as well but the pedal is not sponge at all.

 

If it is a hard pull, it probably is the left front caliper not applying as it should. Possibly a stuck caliper,stuck pins, or a bad hydraulic hose. But it could also be the rear brakes acting up. I would probably look at the left front brake hose first, the dealer may have hung the caliper by the hose when he replaced the hub assembly, not supposed to, but it happens, there may or may not be any evidence of damage to the hose. I don't know how many miles on your truck but it wouldn't hurt to replace both front hoses, always replace in pairs, just to eliminate that as a problem. As they just changed the calipers the pins should be okay, but it wouldn't hurt to check them. If that doesn't fix it you can swap the calipers side to side, the bleeder will be on the wrong end of the caliper so you have to bleed them before actually bolting them down, but if the caliper is bad the pull should then be the other way.
